is a natural gas vehicle fuel oil to natural gas as a gaseous fuel vehicle. Methane content of natural gas is generally more than 90 percentage, is a good vehicle fuel.
1. NGV noun
Oil and gas is natural gas vehicle gaseous fuel as a fuel vehicles. Methane content of natural gas is generally more than 90 percentage, is a good vehicle fuel.

● compressed natural gas (CNG) vehicles. CNG refers to 20.7-24.8 MPa compressed natural gas is stored in high pressure cylinders vehicle. Compressed natural gas (CNG) is a colorless, odorless, high-calorie, lighter than air gases, chiefly methane. Relatively low processing costs, is extremely difficult to liquefy, CNG automotive biggest drawback is the high-pressure cylinder too heavy, bulky and a small amount of gas, takes up the weight of the vehicle more effectively, limits the volume of fuel carried in the car, resulting in continuous driving automobiles mileage short, due to the high additional storage pressure cylinder, also having a certain degree of risk.
● liquefied natural gas (LNG) cars. Cooling the natural gas at atmospheric pressure to -162 deg.] C after forming the LNG liquefaction, which ignition point 650 ℃, explosion limit of the percentage of 5 to 15 percentage higher security. LNG vehicles can be significantly compressed natural gas volume, once inflated, it can travel 500km even more than 1000km, ideal for long-distance transport use. Compared with the CNG vehicles, LNG automotive safety, environmental protection, lightweight vehicle, vehicle driving range and have an advantage.
● liquefied petroleum gas (LPG) is a mixture of hydrocarbons gaseous at normal temperature and pressure, it is heavier than air, higher octane, with mixing, combustion, no soot , lubricants, and other advantages without dilution, can extend the life of the engine, and a gas contained in a large, long mileage.
3. Advantage of natural gas vehicles
● stable combustion, knocking does not occur, and easy cold starting.
● storage of compressed natural gas, reduced pressure, combustion is carried out under strictly sealed state, leakage hardly occurs. Further the cylinder through which a variety of special-destructive testing, safe and reliable.
● compressed natural gas combustion safety, less coke, and the knock reduce air resistance, extend the life of the components in favor of the engine, reduce service and maintenance, greatly reducing maintenance costs.
● engine oil consumption can be reduced.
● CNG compared to gasoline, it can be greatly reduced, carbon monoxide, sulfur dioxide, carbon dioxide and other emissions. And no benzene, lead and carcinogenic and toxic substances harmful to human health.
